Not used my C3200 for a while and when I tried to switch it on I found it was dead...

The FN + D + M method got my into the diagnostic screen and everything there seems fine, trying to do a NAND restore now in the hope that will fix the problems I'm having but it claims there is no SYSC3200.DBK on my CF card (there is) and when I go into the testing menus to see if I can read or write to the CF card I get an error claiming there is no free space (there is plenty). I have tried 2 CF cards and both the same result but the CF card will mount just fine on both Mac and Windows computers.
